Shulou(Shulou.com)06/01 Report--

Autotrace has the following options

SET AUTOTRACE OFF

No AUTOTRACE report is generated. This is the default.

SET AUTOTRACE ON EXPLAIN

The AUTOTRACE report shows only the optimizer execution path.

SET AUTOTRACE ON STATISTICS

The AUTOTRACE report shows only the SQL statement execution statistics.

SET AUTOTRACE ON

The AUTOTRACE report includes both the optimizer execution path and the SQL statement execution statistics.

SET AUTOTRACE TRACEONLY

Similar to SET AUTOTRACE ON, but suppresses the printing of the user's query output, if any. If STATISTICS is enabled, query data is still fetched, but not printed.
